Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020502, here are decompositions:

11 + 1020491 = 1020502
71 + 1020431 = 1020502
83 + 1020419 = 1020502
89 + 1020413 = 1020502
101 + 1020401 = 1020502
113 + 1020389 = 1020502
149 + 1020353 = 1020502
173 + 1020329 = 1020502

Showing the first eight; more decompositions exist.
